LUBRICATOR Specification of Letters Patent. I Patented s e pt, 1'7,I918,

Application filed October 19, 1917. Serial No. 197,420.

To all whom it may concern:

Be it known that I, OLOF SwANsoN, a citizen of the United States, and aresident of Denver, Colorado, have invented a certain new and usefulImprovement in Lubricators, of which the following is a full, clear, andexact description.

.My invention is an improvement in lubricators and relates in particularto certain improvements adapted particularly to flange lubricators ofthe type illustrated and claimed in my Patent No. 1,229,822, issued June12, 1917. The principal objects of my invention are the provision of alubricator having a feed regulator (as distinguished from a regulatingvalve) controlled and operated by vibration transmitted thereto onaccount of the lateral movement of the wheels with respect to the engineor car frame; to associate with such feed regulator a feed controllingvalve automatically operated by the same vibration and constructed topositively close and shut off feed of the lubricant when the engine isstanding still; and to provide certain other improvements in detail ofconstruction and simplicity of parts which will later appear from thisspecification;

In the single sheet.- of drawings accompanying this application andforming a part hereof- Figure 1 is a partial, central, vertical sectionand partial side elevation illustrating my device and the manner ofsupporting and utilizing the same; and

Fig. 2 is a partialhorizontal section and partial plan view showingdetails of the mounting of my device.

Referring to the drawings, in which like characters of referenceindicate like parts in the several views, let 1 designate the lubricantcontainer which is preferably of cylindrical shape with a reduced lowerextremity 2, also of cylindrical shape. A spring pressed cover 3 pivotedon the pin 4:, held in ears 5, closes the upper end of the container anda plug 6 is threaded into the lower end of the container portion 2, toprovide a readily accessible means for cleaning. In one side wall of thereduced lower portion 2 of the container there is formed a port 7 whichcommunicates with a downwardly inclined formed integrally with thecontainer by casting the entire device.

The lower end of the chamber 8 is intechamber 8 preferably riorlythreaded as indicated in the drawings and a lubricant distributingnozzle is screwed therein. This nozzle is preferably a chilled castinghaving a cylindrical opening or bore cored throughout its length, saidbore being of greater diameter toward the surface 10 which is to engagethe flange 11 of the Wheel IV. Within the bore in the nozzle 9 I place apin 12, this pin being of considerably less diameter than the lower 'endof the bore but of only slightly less diameter than the upper or innerportion of the bore. A flattened head 13 serves to prevent the pin 12from falling out of its socket.

At one side of the reduced lower portion 2 of the lubricant container Ilocate a heating chamber in as close proximity as possible to thelubricant regulator and controlling parts. This chamber 14 is providedwith a pipe 15 leading thereto from the exhaust of the air pump or likesource to furnish expanded steam to the chamber 14. Here the steamcondenses, delivering heat at moderate temperature to the containeradjacent thereto and maintaining the lubricant fluid even in the coldestweather. The water of condensation accumulates in the lower portion ofthe chamber until it rises high enough .to run out the downwardlyinclined escape 15,a limited excess of water from which may trickle pastthe pin 16, which substantially but not quite fills the bore of anopening in the plug 17 which closes the lower end of the escape 15. Thisconstruction provides a very restricted opening out of the chamber 14,thus preventing the rapid escape of steam; and the pin 16, which is freeto travel a short distance in its bore, prevents the accumulation ofdirt to clog the restricted opening. A screw plug 18 closes the cleaningport in the chamber 14.

In the upper end of the reduced portion 2 of the lubricant containerthere is screwed a valve cage 20, closed at its lower end save for arestricted port 21- and provided on its lower face with a hexagonalwrench engaging face 22. The cage 20 is screwed up in its socket untilits shoulder 33 engages a similar shoulder formed on the container; theplug is now home with its lower face well above the port 7. Around theupper reduced end of the cage 20 and resting on a shoulder 23 thereon,there is mounted a screen 24 through which the oil passes in leaving themain reservoir in the container.

normally closes the port 21.

A split sleeve 26 surrounds the container 1 atyang appreciable; distanceabove the C6Il3- ter of gravity of the device and this sleeve carries atrunnion 27. bearing 28' sup'-* ports the trunnion in such manner thatthe same is freetdturntherein; and thebea r"- ing 28 is carried a sleeve29 and stands withiit's; axis 'atfright anglesto the aXisof 'said"sleeve.

If it is found that on account of excessive knocking in the journalboxes the nozzle 9 ever flies out so far as to ride on the rim of theflange 11 this can be readily remedied by mounting an adjustable, rigidfinger either on the bracket 32 or on some part of the frame, whichshall overlie the nozzle 9 and prevent its moving a sufticientdistanceradially of the wheel to engage the rim of the flange.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. In a lubricator, a nozzle having a 1011 gitudinalbore therethrough, said bore having a relatively large diameter sectionadjacent its outer end, and a relatively small diameter section adjacentits inner end, a pin within said bore, said pin and the small diametersection of said bore being so propoi-tioned that the pin approximatelystops the flow of lubricant through the small bore section while the pinis quiet but induces and regulates a substantial flow therethrough whensaid pin is in vibration, and means for supplying a. lubricant to theinner end of said nozzle.

2. A lubricator comprising a lubricant container, at discharge nozzleconnected therewith, a vibration actuated valve controlling feed fromsaid container to said nozzle and a vibration actuated feed regulator insaid nozzle.

3. lubricator comprising a lubricant container having a bottom slopingtoward a centrally located port, a ball normally closing said port butadapted to be displaced therefrom by vibration, a nozzle incommunication with said port, and a vibration actuated feed regulator insaid nozzle.

4. A lubricator comprising a lubricant container having a bottom slopingtoward a centrally located port, a ball normally olosing said port butadapted to be displaced therefrom by vibration, a nozzle incommunication with said port, said nozzle having a longitudinal bore,and a pin Within said bore, said bore and pin being so proportioned thatthe pin approximately stops the flow of lubricant through the bore whilethe pin'is quiet but induces and regulates a substantial flowtherethrough when said pin is in vibration.

pin is quiet but induces and r gulates a sub-- stantial flowtherethrough when said pin is in vibration.

6. In a lubricator, a heating chamber, means for supplying steamthereto, a water discharge port leading from said heating chamber, and apinfree tovibrate in said port.
